This could be an interesting solution, I forgot that multiple geometries/meshes can be loaded with the "Merge" script command. I could see problems at the interface between the bottom face of the heatsink and the pre-meshed component (the elements would be coincidental to the face, but not part of the face). I'll have to look more into how to rebuild the geometries (another twist here is that I'm using a system that writes BREP files for Gmsh, and not using the native modelling capabilities).
